系统解析：M: We're going down to the sports center to work off some of that big lunch we had. Anyone wanna come?
W: What have they got there?
M: They've got a swimming pool, a weight room, aerobics classes, tennis courts, and a track out back.
W: I'm going to the aerobics class.
M: A good idea. Aerobics is good for women. But don't you want to do a few laps in the pool to warm up?
W: I didn't bring my swimsuit.
M: Up to you. I'm going to do some running on the track for a few minutes before I hit the gym.
W: Running makes me a little tired. I don't like it.
M: Well, maybe you should do a little running. That's better than nothing.
W: OK, let's go find the locker room and get started.
